Abstract

A first aspect of the present invention includes an N-persistent-mode pointing device and a 2N-mixed-mode pointing device. A second aspect of the present invention is an unconventional method for generating target-motion signals with common motion controls. This method utilizes a qualification-rule-based dynamic mapping of the present invention. A third aspect of the present invention combines the multi-mode designs and the dynamic mapping.

1. A method for controlling a plurality of functions of a computer, comprising the steps of:

(a) providing a predetermined number of user-operable controls that generate control signals reflecting user operations,

(b) providing a correspondence with a predetermined number of persistent modes, said correspondence associating each said control to a said function in each said persistent mode,

(c) providing a mode-selection means comprising at least one momentary switch that generates a first signal when activated and a second signal when deactivated,

(d) providing a mode-selection protocol where a predetermined unique sequence of said first signal and second signal within a predetermined period of time indicates a specific mode-selection request,

(e) using said mode-selection means to indicate a selected mode from all said persistent modes according to said mode-selection protocol,
